Drawing: Cold-worked steel products

The strength that a steel material needs to exhibit will depend on how the steel is to be used. One way of increasing the strength of steel is to subject it to the mechanical process of cold drawing. Cold drawing not only affects the surface of the steel, making it more finely grained and lustrous in appearance, it also influences the mechanical properties of the material. The strain hardening that occurs in the cold drawing process makes the material harder and more magnetic.

Cold drawing is a bulk deformation process in which the diameter of the steel bar is reduced through plastic deformation. Drawing can be carried out to reduce the diameter or the wall thickness of the stock, or to improve the material’s surface quality, strength or dimensional tolerances. The bright steel products produced by cold drawing typically exhibit strain hardening. After drawing, the bars are straightened on straightening machines by subjecting them to multiple bending and reverse bending operations in the elastic-plastic range.

An extensive portfolio of rolled steel products

No matter whether our customers need a microalloyed steel, an engineering steel with added lead, or a lead-free, free-cutting steel designed for optimum machinability, Steeltec offers a wide range of rolled steel grades in a large range of sizes. This coupled with its ability to precisely modify and analyze the chemical composition of its steels, make it one of the key market players in the free-cutting steel segment. As Steeltec’s unalloyed steels are free from unwanted inclusions, these high-purity steels are ideal for the manufacture of pressure-resistant components. The lead-containing steels, in contrast, exhibit a homogeneous distribution of manganese sulfide inclusions, resulting in free-cutting steels with superb machining characteristics. On request, Steeltec can also supply rolled steel that can be machined directly. The company also offers an extensive portfolio of resulfurized steel grades, each with a carefully controlled sulfur content of at least 0.02 percent.

A flexible project partner delivering quality services on schedule in the rolled steel segment

An "off-the-shelf" steel is not always suitable for your own very specific requirements. That's why we understand service as more than just short response times and on-time delivery with short lead times: We respond flexibly to special customer requests. This is made possible by our alignment to a rolling plan, which makes us the ideal partner for project-related orders. At the same time, a consistent team of consultants in field and office sales as well as in engineering takes care of the intensive individual support in every project.

Will the part or component be machined?

Around 85% of the costs in parts manufacturing are attributable to process costs. It is therefore worthwhile to optimize these costs with the targeted use of materials. Steeltec free-cutting steels are optimized for machining. Steeltec has also developed high-strength special products with outstanding machining properties. Short chip breaking, longer tool life and high uniformity across batches open up new possibilities in the design of manufacturing processes.

More about machining

Will the part or component be subjected to particular large stresses?

Materials for highly stressed parts must not only be outstandingly machinable, but also withstand high loads. A typical load - for hydraulic components, for example - is dynamic stress. To withstand it, users need a steel with a good ratio of strength and toughness.

More about static and dynamic loading

Will the part or component be processed asymmetrically?  

High dimensional stability and uniform machining behavior are decisive for an economical and plannable manufacturing process. The manufacturing costs per part are decisive, especially in high-volume production. Our low-distortion steels are designed to meet specified geometries and tolerances and minimize financial risk.

More about low-distortion steels

Will the part or component be subject to a cold-forming process?

The required properties - for example in terms of machinability, cold formability or weldability - can be precisely adjusted to customer specifications during the process. Thanks to very good cold forming properties, steels are formed into components, e.g. fasteners, by cold forming. Depending on the application requirements, they exhibit high strength and high durability. To achieve this, the materials must combine high initial strength with good formability. Special steels from Steeltec enable efficient and resource-saving production.

More about cold forming

Will an additional heat-treatment stage be carried out?

Thanks to in-depth chemical analysis, Steeltec is able to design materials in such a way that desired mechanical-technological component properties are achieved after heat treatment. This results in a wide range of high-quality steel designed to meet individual customer requirements. In the bright steel sector, we will be pleased to advise you on what needs to be taken into account in the case of additional hardening.

More about heat treatment

Will the part or component be welded?

Welding is particularly important for chains and structural grades, but also for applications such as the manufacture of wire baskets. Steeltec's rolled steels can be welded using various techniques. Welding requires materials that are alloyed. In addition, just as in bending, the steel needs a certain hardness, but it must be possible to machine it. And it must be possible to heat it without creating too much stress.
